To all '4c hom ci may conce/fn Be it known 'that I, CHARLES F. BRYAN, a citizen of theUnited States, residing at Hetland, in the countyof Kingsbury and State of South Dakota, have invented certain new and useful Improvements in a Snowplow, of which the following is a specication.

This invention relates to new and useful improvements in snow plows and hasior its principal object to provide a simple and eilicient means for removing snow from' a road or highway, means being associated therewith for discharging the snow removed from the road to the side thereof.

A further object of the invention .is to provide a snow plow of the above mentioned character, wherein means is provided for breaking up the lumps of snow before the 'saine reachesA he blower fan wherebythe same may properly receive and discharge the snow in such a manner as topreventV attached to a tractor the clogging of the snow plow,` i y Y A still further object of the inventionis to provide a snow plowof the above mentioned character, which is of such a construction as to enable the same to be readily for' operating the same, means being provided for actuating the ro tary cutter and blower fan of the plow simultaneously. y A.

A further object is to provide a snow plow of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposesy for which it is designatd. p

Other objects and advantages of this invention will become apparent during the course of the following description. l

. ln the accompanying drawings forming part of this specification and. in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of myimproved snow plow. l

Figure 2 is a rear, elevation thereof.

Figure 3 is a front elevation thereof, and

Figure 4 is a vertical section showing the arrangement of the rotary cutter and blower fan.

In the drawings wherein for the purpose of illustration is shown the preferred einbcdiment of my invention, the numeral 1 designates a substantially rectangular sha casing, the trout tace of which is rlet pipe whereby the former open. Arranged on the lower edge of the forward portion of the casing is the scoop 2, the purpose of which is well known in the. art; Extending centrally through the casing is the driven shaft 3 on the forward end of which is supported and adapted to rotate therewith, the rotary cutter ,designated generally by the numeral 4.

` The rotary cutter comprises the enlarged annular rim 5.and the hub ortion 6 which is` mounted on theouter orward end of the shaft 3. Cutter blades such as are il'- lustrated at 7 4extend radially between the hub portion 6 and the rim 5 in the manner more clearlyv illustrated in Figure 3 of the drawings. Suitable bracing means such as illustrated at 8 extend Jfrom thel annular rim to a sleeve 9 which is secured onthe 4shaft 3 at a point adjacent the hub portion 6 in the rotary cutter 4 in the manner more clearly illustrated inFigure 4 o the drawings. 'lhe cutter is `ada ted to rotate within the casing 1 in suc a manner as to break up the lumps of snow which are -deliveredf to the cutter by the scoo ,2 as the snow plow Ymoves lalong the -roa or highway.

:The bottom of the casing is inclined rearwardly as illustrated at 1() to provide the accumulation and depositing ofthe snow therein. Communicating with the back of the casing adjacentv the lower central portion. thereof is the fan casing 11. Ex nding through the casing 11 is' the sha1 12 and mounted on the forward end` thereof and arrangedxwithin the fan casing 11 is the blower fan 13 which is yadapted to rotate with the shaft'in' the'manner hereinafter to be more fully described. y

The fanor blower casing 11 is provided with an outlet-pipe 14 whichy extends upwardly therefrom adjacent the rear portion of the casing 1 and a discharge pipe such as illustrated at 15 is movably supported on the upper end of the outlet pipe 14, a supporting collar such as illustrated at 16 being provided for enabling thedischarge pipe to vbe rotatably supported on the'outy may be moved in any desired position. The provision of the outlet and discharge -pipe provides a means whereby the snow will be delivered therethrough by the rotary fan andv will cause the snow to be discharged along the side of the road or highway when the snow plow is in use.

The shaft 12 a'sits rear end supported in a suitable bracket 18 which is also mounted on the rear portion of the fan casing 11 in the manner more clearly illustrated in Figures 1 and 2 of the drawings. Suitable bearings such as areillustrated at19 and 20 respectively are secured to the rear portions of the casing and fancasing 11 for cooperation, with the shafts therethrough. v. shown at 21v are 3 and 12 respectively which extend Grease cups such as are provided for each of the bearings for the purposes wellknown in the art.

. Y Journ'aled in suitable brackets 22 and 23 respectively which are supported by the fan casing lland extending transversely to the shaft?) is thev shaft One end of the vshaft 24 is provided the pulley wheel 25 v which is adapted topbe driven by any suitablev source of power from the tractorvupon which the snow plow is mounted and on the `opposite end of the vshaft 424: is provided a beveled gear 26, This beveled gear isv adaptgear 27 mounted cutter 4 arranged on the forwardfend thereof and disposed withinI the casing 1. For the purpose o f simultaneously rotating thefan 13, Iprovide the shafts tively with aligning sprocket wheels 28 and `219v respectivelyand over which is trained V't iey procket chain 30.` It will thus be seen that when the shaft 24 is actuated through the medium of the pulley 25,- the shafts 3 and 12 respectively will be simultaneously operated for actuating the rotary cutter and Vroved snow plow r'efly stated as ollowszThe plow is ada ted to be supported onthe forward end o atractor in any suitable'manner and ulley wheel25 is connected to` the The operation of my .iin

the same to be easily and readily placed in an operative position and when in use will eiiiciently remove the snow from a road or highway. A snow plow of the above mentioned character, may be manufactured at a very low cost and will further be strong and durable.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claims.

I-Iavn thus described the invention, what I c aim is 1. A snow plow com rising a casing, a scoop rovide onv the ower forward edge thereo the front face of the casing be'n o en, a shaft extending centrally throughY t e casing,` a rotary cutter supported on thel forward end of the shaft and disposed within the casing, a fan casing arranged o n the rear portion of the aforementioned casing and communicating with -the Alower portion thereof, a shaft extending through the fan casing, a rotary fan supported thereon and disposed within the on said fan casing for supporting said shafts, a beveled gear mounted on the rotary cutter shaft, a drive shaft supported on the fan casing, means associated with one end of the drive shaft for operating the same a beveled gear on the op osite end of the shaft for cooperation with the beveled gear on the rotary cutter shaft, aligning sprocket wheels provided yon therotary cutter shaft and the fan shaft, a sprocket chain extending over the sprocket wheels whereby the, rotary fan and rotary cutter are actuated simultaneously, and an outlet. pipe .extending upwardly from' the 2. A snow low comprising a substantially rectangular casing open at its front, a scoop on t e lower forward edge thereof, the bottom of the casing being inclined rcnrwardly, a shaft extending centrally throu rh the casing, a rotary cutter mounted on tie forward vend of the shaft and disposed within the casing, a -fan casing arranged on the rear portion of the aforementioned casing and communicating with the lowei' portion thereof, a shaft extending through the fan casing, a rotary fan supported thereon and disposed within the fan casing, means for rotating the shaft simultaneously, and an outlet pipe extending ,from the fan casing.

testlmony whereof I affix my signature.
